FIREARM.

Application filed July 7, 1915.

To all whom it may concern: D

Be itknown that I, Jon RUnLorr, a citizen of. the United States,residing at Baggs, in the county of Carbon and'State of Wyoming haveinvented certain new and useful Improvements in Firearms, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to certain improvements in fire arms and hasrelation more particularly to a device of the general character of amagazine type; and it is an object of the invention to provide a noveland improved fire arm wherein the magazine is p sitioned within the gripor stock and wherein the shells are discharged through said grip orstock.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved fire armwhereby certain important advantages are attained and the device isrendered simpler, less expensive andotherwise more convenient andadvantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in theappended claims.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a view, partly in section and partly inelevation, of a fire arm constructed in accordance with an embodimentofmy invention; Fig. Zis a transverse sectional View taken through thestock or grip of the fire arm as herein disclosed," Fig. 3 is alongitudinal sectional view taken through the re ceiver and adjacentportions of the barrel and grip, with 'the major portion of the gripshown in elevation; Fig. 4 is a horizontal longitudinal sectional viewtaken through the barrel and receiver as herein embodied. with thebreech block shown in retracted position; Fig. 5 is a view inperspective, detached. of a locking vmember herein embodied; Fig. 6 is afragmentary view in rear elevation of a magazine herein emplcycd;

and Fig. 7 is a fragmentary view in front I elevation of the magazineopposite to that shown in Fig. 6.

As disclosed in the accompanying crawlugs, 1 denotes the receiver, 2 thebarrel, and

" 2- the grip or stock, said grip or stock being hollow and incommunication with the in- Specification of Letters Patent.

terior of the receiver and having its lower end open and said grip orstock is also divided into two compartments a and b by the partition 4extending in a direction longitudinally of the firearm, the compartmentav constituting the magazine chamber and the compartment 6 constitutingan ejecting chamber through which the shells are adapted The partition 4gradually increases in thickness from itslower end and adjacent itsupper end is provided with an opening 5 in which the plunger 6 works andin which is mounted the trigger 7.

W'ithin the receiver chamber and engaged with the upper end of thepartition l is the breech block 8 of the blow-back type with whichcoacts, in a conventional manner, the recoil spring 9 and disposedthrough said breech block is the hammer 10 with which coacts the firingspring 11, said hammer being retracted under the influence of therearward movement of the breech block and consequently placing thefiring spring 9 under tension. The hammer is maintained in its retractedposition through the medium of the sear 12 coacting with a lug 14carried by the hammer and said sear automatically on gages the lug underthe influence of the spring 15. The trigger 7 coacts with the sear 12 ina conventional manner.

16 denotes a safetymember engageablewith the sear in advance of itspivot and adapted to lock the same against movement under the influenceof the trigger 7 and, as herein disclosed, said safety member is carriedby the shaft l7 projecting exteriorly of the stock or grip 3, theexterior portion of said shaft being provided'with a finger-piece 18whereby the safety member may be adjusted into or out: of the engagementwith the scan The breech block 8 has pivotally engaged therewith aconventional extractormemher '19 adapted to coact with the flange of theshell S in a well-known manner and to withdraw said shell when thebreech block is forced rearwardlv under the influence of the recoil andwhereupon said shell is adapted to be ejected through the compart ment ZThe inner face of the breech block 8 I provided with a longitudinallydisposedgroove 20 in which is pivotally mounted the feed member or arm21, the forward ex tremity of which being under'the influence of thespring 22, whereupon-said feed memher or arm will be caused to engagebehind the uppermost cartridge within the magazine M Within the chambera as the breech block 8 is forced rearwardly whereupon said cartridgewill be properly positioned Within the barrel 2, or more particularlythe firing chamber thereof, when the breech block is returned under theinfluence of the recoil spring 9. The magazine M is of conventionalconstruction and a' detail description thereof is therefore believed tobe unnecessary.

The breech block 8 is provided with the depending lip 23 with which theplunger 6 coacts in order to initially adjust the hammer 10 into firingposition. I also find it of advantage to provide the outer or rear endof the receiver 1 with an opening 24 through which the hammer 10 maypass so that no obstruction will be offered to the retracting movementof said hammer.

From the foregoing description, it is thought to be obvious that a firearm constructed in accordance with my invention is of an extremelysimple and comparatively inexpensive nature and is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and it will also be obvious that my invention issusceptible of some change and modification without material departurefrom the scope of the appended claims and for this reason I do not wishto be understood as limiting myself to the precise arrangement andformation of the several parts herein shown in carrying out my inventionin practice.

I claim:

1. The combination", in an automatic fire arm, with a receiver and ahollow grip in communication therewith and the lower end of the gripbeing open, a partition dividing the grip into two compartmentslongitudinally thereof, a magazine insertible in one of saidcompartments, a spring-pressed and recoil operated breech block slidablyen gaged with the upper end of the partition, an extractor membercarried by the breech block for extracting the shell and delivering thesame within; the ejecting compartment of the grip, and a feed armcarried by the breech block engageable with the cartridge within themagazine for forcing the cartridge into firing position, the oppositefaces of the partition being arranged in downwardly converging planes.

2. The combination, in an automatic fire arm, with a receiver and ahollow grip in communication therewith and the lower end of the gripbeing open,a partition nally thereof, a magazine insertible in one ofsaid compartments, a spring-pressed and recoil operated breech blockslidably engaged with the upper end of the partition, an extractormember carried by the breech block for extracting the grip, and a feedarm carried by the breech block engageable with the cartridge within themagazine for forcing the cartridge into firing position. In testimonywherof I hereunto afiix my signature in the presence of two witnesses.
